Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, and in particular to a Peak racket. Background Technology

[0002] Existing Peak rackets are usually composed of an integrated head and handle. To meet the requirements of grip comfort and anti-slip, the handle part generally adopts a fixed covering structure, that is, a layer of foam material, rubber or wrapping tape is tightly wrapped around the outside of the handle. This type of cover is mainly fixed to the internal handle part of the racket body by means of strong adhesive bonding, heat shrink tubing shrink fixation, etc.

[0003] However, as Peak rackets accumulate dirt and wear due to sweat and stains during use, the existing racket covers are difficult to clean or replace thoroughly. If the cover needs to be removed or replaced, the original structure of the cover often needs to be completely destroyed before a new cover can be installed. This results in high maintenance costs, waste of resources, and difficulty for users to flexibly change the cover according to different needs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a Peak racket to solve the technical problems of high maintenance costs, resource waste, and difficulty for users to flexibly change the outer shell according to different needs of existing Peak rackets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

When the elastic telescopic structure is in the first state, its protruding part is locked into the corresponding locking hole to lock the rod and the handle in the axial direction.

[0012] In some embodiments, the elastic telescopic structure includes an elastic element and a telescopic block; the telescopic block is slidably disposed in the telescopic groove along the radial direction of the rod; the elastic element is connected to the groove body of the telescopic block and the telescopic groove, and is used to provide the telescopic block with an elastic force to move it outward from the telescopic groove.

[0013] In some embodiments, the locking member further includes an adjustment structure disposed on the ball portion, the adjustment structure being connected to all the telescopic blocks and used to control all the telescopic blocks to switch between the first state and the second state.

[0014] In some embodiments, the control structure includes a rotating ball, a winding reel, and multiple connecting lines; The rotating ball is rotatably disposed on the outer side of the ball portion; The winding reel is disposed inside the ball and is coaxially and fixedly connected to the rotating ball. One end of each of the connecting lines is connected to the reel, and the other end passes through the inside of the rod and is connected to one of the telescopic blocks; The rotating ball can drive the winding reel to wind up or release the connecting line, thereby simultaneously pulling all the telescopic blocks to retract to the second state, or allowing them to return to the first state under the action of the elastic element.

[0015] In some embodiments, the cross-section of the handle portion is non-circular; the cross-sectional shape of the receiving cavity matches the handle portion, and the receiving cavity and the handle portion are in clearance fit or transition fit.

[0027] Existing Peak rackets are usually composed of an integrated head and handle. To meet the requirements of grip comfort and anti-slip, the handle part generally adopts a fixed covering structure, that is, a layer of foam material, rubber or wrapping tape is tightly wrapped around the outside of the handle. This type of cover is mainly fixed to the internal handle part of the racket body by means of strong adhesive bonding, heat shrink tubing shrink fixation, etc.

[0028] However, as Peak rackets accumulate dirt and wear due to sweat and stains during use, the existing racket covers are difficult to clean or replace thoroughly. If the cover needs to be removed or replaced, the original structure of the cover often needs to be completely destroyed before a new cover can be installed. This results in high maintenance costs, waste of resources, and difficulty for users to flexibly change the cover according to different needs.

[0029] Please see Figure 1 , Figure 2 and Figure 7 This invention provides a Peak racket, comprising: a racket body 10, including a hitting part 11 and a handle part 12 connected to the hitting part 11; a handle sleeve 20, including a detachably configured first half sleeve 21 and a second half sleeve 22, the first half sleeve 21 and the second half sleeve 22 forming a receiving cavity 26 for fitting the handle part 12; and a locking assembly 30 connected to the racket body 10 and / or the handle sleeve 20 to fix the handle part 12 and the handle sleeve 20 relatively.

[0030] For example, the striking part 11 is the portion of the racket body 10 used to strike the pickle. It is typically a nearly rectangular plate-like structure made of a rigid composite material, and its surface may be covered with a rough surface to increase friction or have structural holes to reduce wind resistance. For example, the handle part 12 is the portion of the racket body 10 used by the user to grip the racket. It is typically a cylindrical body made of the same or similar material integrally formed or fixedly connected to the striking part 11. Its cross-section is preferably non-circular to cooperate with the handle sleeve 20 to prevent relative rotation.

[0031] For example, the grip sleeve 20 is detachable from the handle portion 12. That is, the grip sleeve 20 can be fitted onto the handle portion 12 by sliding, snapping, or threading, and can be completely removed without damaging the original structure by reversing the operation. For example, the grip sleeve 20 is used to provide a grip feel for the user. It can be left-hand grip, right-hand grip, Eastern grip, Western grip, or various styles with different hardness, texture, and weight. The user can quickly change grip sleeves by simply selecting any style of grip sleeve 20 and fitting it along the axis of the handle portion 12 to adapt to different usage habits, hand hygiene conditions, or tactical needs. For example, the grip sleeve 20 is composed of a first half sleeve 21 and a second half sleeve 22. Through the detachable connection of the first half sleeve 21 and the second half sleeve 22, the user does not need to pass the entire grip sleeve 20 through the end of the handle part 12. Instead, the user can place the two half sleeves on both sides of the handle part 12 and then close them together, which greatly simplifies the assembly process and avoids the assembly difficulties caused by interference fit or size limitations of the traditional straight-tube grip sleeve 20.

[0032] For example, the sides of the first half-piece 21 and the second half-piece 22 can be provided with mutually cooperating snap-fit ​​structures so that when the first half-piece 21 and the second half-piece 22 are connected, they can be quickly snapped together to form a complete annular handle sleeve 20. For example, the snap-fit ​​structure may include an elastic hook provided on the side of the first half-piece 21 and a corresponding slot provided on the side of the second half-piece 22. When the first half-piece 21 and the second half-piece 22 are radially closed, the elastic hook deforms under pressure, slides into the slot and returns to its original shape, thereby achieving a locking connection between the two. This design allows users to assemble and disassemble the handle sleeve 20 by hand without using additional tools, improving the convenience of operation.

[0033] For example, the locking component 30 can connect the handle sleeve 20 and the hitting part 11, thereby limiting the relative positioning of the handle sleeve 20 and the racket body 10. For instance, the locking component 30 includes a screw with one end fixed to the end of the handle sleeve 20, which, after being screwed in, extends into the hitting part 11 and presses against the end face of the handle sleeve 20. Alternatively, the locking component 30 can also connect the handle sleeve 20 and the handle part 12, thereby limiting the relative positioning of the racket body 10 and the handle sleeve 20. For instance, the locking component 30 includes a screw with one end fixed to the end of the handle sleeve 20, which, after being screwed in, extends into the handle part 12 and presses against the end face of the handle sleeve 20.

[0034] For example, the installation steps of the handle sleeve 20 in this embodiment may include: first, placing the first half sleeve 21 and the second half sleeve 22 on opposite sides of the handle portion 12 respectively; then, closing them radially so that the first mating member 31 and the second mating member disposed on their inner sides engage with each other in the through hole 13 of the striking portion 11, thereby completing the connection and circumferential positioning of the handle sleeve 20 itself; finally, installing the locking component 30 to the handle sleeve 20 and the handle portion 12 to achieve axial fastening.

[0035] It is understood that the Peak racket of this embodiment, by setting a detachable handle sleeve 20 and a corresponding locking member 32, allows the handle sleeve 20 to be easily and without damage to be installed and removed. This solves the technical problems in the prior art caused by the non-removable handle sleeve 20, such as cleaning difficulties, inability to flexibly replace it according to individual needs, and high maintenance costs and waste of resources. Furthermore, the design of the handle sleeve 20, which is formed by the detachable combination of the first half-sleeve 21 and the second half-sleeve 22, avoids the problem of high friction and difficulty in fitting the straight-tube outer sleeve during assembly.

[0036] Please see Figure 2 as well as Figures 4 to 7 In some embodiments, a recess 23 is provided on the outer periphery of the handle sleeve 20. The recess 23 forms a first spiral undulating surface 25 adapted to be held by the left hand, or a second spiral undulating surface 24 adapted to be held by the right hand.

[0037] For example, the recess 23 may be formed by directly molding a groove during the mold design stage of the handle sleeve 20; or, the recess 23 may be a natural transition area formed between adjacent protruding structures. For example, the spiral directions of the first spiral undulating surface 25 and the second spiral undulating surface 24 are opposite. For instance, when viewed from the end of the handle sleeve 20 toward the hitting part 11, the surface adapted for right-hand grip extends clockwise around the ball, while the surface adapted for left-hand grip extends counterclockwise around the ball. This direction corresponds to the wrapping direction and pressure distribution of each finger when the corresponding hand type naturally grips the racket.

[0038] For example, when the first half-set 21 and the second half-set 22 are connected to form the receiving cavity 26, the recesses 23 provided on the first half-set 21 and the second half-set 22 should be smoothly connected at their mating boundaries. This requires that the first and second half-sets 22 have precise fitting dimensions and contours in mold manufacturing, so that after closing, the recesses 23, which originally belonged to two parts, can be seamlessly connected to form a continuous, complete, and stepless ergonomic curved surface. For example, small rounded corners or guide bevels can be provided at the mating edges of the first and second half-sets 22 to guide their accurate alignment and eliminate any slight misalignment that may exist after assembly, ensuring consistency and comfort in the grip.

[0039] Understandably, the design of the first spiral undulating surface 25 and the second spiral undulating surface 24 significantly improves the fit between the grip 20 and the user's hand anatomy. For example, the recessed portion 23 can better accommodate the finger joints, while the protruding portion between adjacent recessed portions 23 can more stably rest against the soft tissue of the palm and fingertips, thus providing better comfort, stability, and power transfer efficiency during prolonged gripping and powerful swings, and effectively relieving fatigue. Users can choose to replace the grip 20 with the corresponding spiral direction according to their left-handed or right-handed gripping habits to achieve personalized adaptation.

[0040] like Figure 13 and Figure 14 As shown, in some embodiments, a grip positioning part 27 is provided on the outer periphery of the handle sleeve 20. The grip positioning part 27 is formed by protruding outward from the outer periphery of the handle sleeve 20, and is used to provide tactile positioning and support for the user's fingers and / or the web of the hand.

[0041] For example, the grip positioning part 27 can be a smoothly contoured ridge independent of the recess 23, which is disposed on the first spiral undulating surface 25 or the second spiral undulating surface 24 corresponding to the area of ​​the user's palm or a specific finger root. For example, for a handle 20 adapted for right-handed grip, the grip positioning part 27 can be disposed in the upper right area of ​​the handle 20 (with the racket head facing upwards), so that the user's right palm can naturally rest against and be positioned there.

[0042] For example, the grip positioning part 27 may include a first protrusion structure that matches the thumb and a second protrusion structure that matches the middle or index finger. When the user holds the handle sleeve 20, the user can use the fingers to match and grip the grip positioning part 27 to correctly grip the handle sleeve.

[0043] Understandably, the grip positioning unit 27 not only provides additional comfort and padding support, but its core function lies in actively "guiding" and "correcting". Specifically, the grip positioning unit 27 provides a physical reference point for the user's hand, ensuring that the hand shape can quickly and accurately return to the optimal position each time the racket is gripped. This is especially helpful for beginners to establish correct muscle memory, or for all users to quickly find the standard grip through touch when fatigued after a long game, thereby improving the consistency, stability and power transfer efficiency of the shot, and reducing the risk of wrist injury caused by incorrect grip.

[0044] Furthermore, the grip positioning part 27 can be integrally formed with the recessed part 23 on the handle sleeve 20. In an embodiment where the handle sleeve 20 is composed of a first half sleeve 21 and a second half sleeve 22, the grip positioning part 27 can be symmetrically or asymmetrically disposed on the first half sleeve 21 and / or the second half sleeve 22. When the first half sleeve 21 and the second half sleeve 22 are closed, they together form a complete and smooth raised contour.

[0045] In some embodiments, the striking part 11 has a through hole 13, which extends through the striking part 11 along its thickness direction.

[0046] For example, the axis of the through hole 13 is typically perpendicular to the hitting surface of the hitting section 11, that is, it passes through the normal direction of the hitting surface. For example, opening the through hole 13 can at least reduce wind resistance during racket swing, and also help to reduce the overall weight of the racket and improve control. For example, there is usually a gradually narrowing transition area between the hitting section 11 and the handle section 12, and the through hole 13 can be set in this transition area. This position is closer to the racket's center of gravity change area, which helps to maintain the overall balance of the racket.

[0047] It should be explained that creating a through hole 13 in the striking section 11 is a mature technical method, the main purpose of which is to optimize the aerodynamic performance and weight distribution of the racket. In some preferred embodiments of the present invention, the through hole 13 may be further endowed with additional structural functions, but this does not affect its basic properties as a weight-reducing and drag-reducing hole.

[0048] like Figure 2As shown, in some embodiments, the locking component 30 includes a first mating member 31 disposed inside the first half-sleeve 21 and a second mating member disposed inside the second half-sleeve 22; when the first half-sleeve 21 and the second half-sleeve 22 surround the handle portion 12, the first mating member 31 and the second mating member are engaged with each other in the through hole 13 to connect the first half-sleeve 21 and the second half-sleeve 22 and restrict the circumferential rotation between the handle sleeve 20 and the handle portion 12.

[0049] For example, the first and second mating parts 31 can be designed as complementary hook-shaped or tenon-and-mortise structures. For instance, the first mating part 31 can be an elastic hook with an inclined guide surface, and the second mating part can be a slot or platform matching the shape of the hook. When the first and second halves 22 are closed, the hook undergoes elastic deformation under the guidance of the guide surface, slides into the slot, and resets, emitting a clear "click" sound to indicate that the connection is in place, thus achieving a detachable mechanical locking between the two. Alternatively, the first and second mating parts 31 and 22 can be magnetically attracted terminals. When the first and second halves 22 are closed, the first and second mating parts 31 contact and magnetically adhere to each other.

[0050] For example, the first mating member 31 and the second mating member can be fitted with a transition fit or a small clearance fit with the inner wall of the through hole 13. After the first mating member 31 and the second mating member are engaged inside the through hole 13, the outer contour of their assembly is in contact with or adjacent to the inner wall of the through hole 13. Thus, the rigid side wall of the through hole 13 directly limits the assembly of the first and second mating members. Therefore, any force that attempts to rotate the handle sleeve 20 around the handle portion 12 will be transmitted to the inner wall of the through hole 13 through the first and second mating members and effectively blocked by it, fundamentally preventing the handle sleeve 20 from loosening during use.

[0051] It is understood that in this embodiment, the through hole 13, which has the functions of weight reduction and wind resistance reduction, is used as the structural connection and limiting window of the first and second docking parts. The user only needs to close the first and second half-sets 22 to simultaneously complete the mutual connection and anti-rotation locking.

[0052] In some embodiments, the handle portion 12 has a non-circular cross-section; the cross-sectional shape of the receiving cavity 26 matches that of the handle portion 12, and the receiving cavity 26 and the handle portion 12 are in clearance fit or transition fit.

[0053] For example, the cross-section of the handle portion 12 can be elliptical or quasi-elliptical, and the shape of the receiving cavity 26 corresponds accordingly. The ratio of the major axis to the minor axis can be optimized based on ergonomics, providing a natural grip and pointing feel while effectively preventing the circumferential rotation of the handle sleeve 20 relative to the handle portion 12 through its non-rotational symmetry geometry. For example, the cross-section of the handle portion 12 can also be polygonal, such as a regular hexagon, rectangle, or polygon with rounded corners. In this case, the receiving cavity 26 has an inner contour that matches the shape of the cross-section of the handle portion 12, and its angular or planar mating structure can provide clear circumferential positioning, thereby achieving a reliable anti-rotation effect.

[0054] like Figure 3 , Figure 4 And such as Figures 8 to 12 As shown, in some embodiments, the locking assembly 30 includes a locking member 32, which includes a ball portion 322 and a rod portion 321; the handle portion 12 has a blind hole 121 at one end away from the striking portion 11 along its axial direction, the rod portion 321 is inserted into the blind hole 121, and one end of the rod portion 321 is located inside the blind hole 121, while the other end extends outside the blind hole 121 and is connected to the ball portion 322; the ball portion 322 is detachably connected to the end of the handle sleeve 20.

[0055] For example, the diameter of the ball part 322 is larger than the diameter of the receiving cavity 26. When the ball part 322 is connected to the handle sleeve 20, the ball part 322 will completely cover the opening of the receiving cavity 26 away from the hitting part 11, which plays a role in sealing and decorating the receiving cavity 26. It can prevent foreign objects such as dust and sweat from entering the interior of the handle sleeve 20 through this opening, while making the appearance of the racket tail complete and smooth.

[0056] For example, the ball portion 322 and the handle sleeve 20 can be connected by a thread. For instance, the ball portion 322 has an internal threaded hole at its center on the side facing the handle sleeve 20, one end of the rod portion 321 is fixed in this internal threaded hole, and the end of the handle sleeve 20 away from the striking part 11 has an external thread matching the internal thread. Tightening the ball portion 322 allows for a secure connection or separation from the handle sleeve 20. Alternatively, the threaded connection can be designed with an internal thread on the inner side of the end of the handle sleeve 20 and a corresponding external thread on the ball portion 322. It should be noted that when the handle sleeve 20 is formed by connecting the first half-sleeve 21 and the second half-sleeve 22, the threaded structure at its end is formed by both the first half-sleeve 21 and the second half-sleeve 22, ensuring a stable connection between the ball portion 322 and the handle sleeve. Further details are omitted here.

[0057] For example, the shaft portion 321 and the ball portion 322 are coaxially arranged, that is, the axial extension of the shaft portion 321 passes through the center of the ball portion 322.

[0058] For example, to achieve axial position adjustment of the grip sleeve 20 relative to the handle portion 12 to meet the user's personalized needs for racket length and balance point, the shaft portion 321 and the blind hole 121 are configured for an axially sliding insertion fit. To accommodate this adjustment and ensure that the grip sleeve 20 remains reliably connected to the racket body 10 during adjustment, the through hole 13 in the hitting portion 11 includes an elongated hole extending axially along the handle portion 12. Correspondingly, the first mating member 31 and the second mating member, located inside the first half-sleeve 21 and the second half-sleeve 22, can engage with each other within the elongated hole, allowing the assembled unit to slide axially along the path of the elongated hole. This allows the first mating member 31 and the second mating member to move synchronously within the elongated hole when the user changes the axial position of the grip sleeve 20 by operating the locking member 32, always remaining inside the through hole 13, thereby continuously providing circumferential restraint on the grip sleeve 20 and ensuring connection stability at any position during and after adjustment.

[0059] Understandably, the locking member 32 inserts into and is positioned in the blind hole 121 of the handle part 12 via its shaft 321, and then achieves a detachable and secure connection with the end of the handle sleeve 20 via its ball part 322, thus firmly locking the handle sleeve 20 onto the handle part 12. This achieves the core function of quick assembly and disassembly of the handle sleeve 20. Its ball part 322 also serves as a human-computer interaction interface, facilitating user operation and enhancing the grip feel and overall aesthetic appeal of the product. Furthermore, the sliding engagement between the shaft 321 and the blind hole 121, along with the linkage design with the elongated hole, the first connecting member 31, and the second connecting member, allows the extension length of the handle sleeve 20 to be infinitely or multi-level adjusted according to the user's personalized needs. This allows users to customize the overall length, swing weight, and balance point of the racket to precisely match their power, arm length, technical style, and tactical preferences, greatly expanding the product's adaptability and performance potential, and realizing the transformation from "the person adapting to the racket" to "the racket adapting to the person."

[0060] In some embodiments, the cross-section of the rod 321 is non-circular; the blind hole 121 is clearance-fitted or transition-fitted with the rod 321.

[0061] For example, the cross-section of the rod 321 can be elliptical or quasi-elliptical, and the shape of the blind hole 121 corresponds accordingly. For example, the cross-section of the rod 321 can also be polygonal, such as hexagonal, rectangular, etc., and the blind hole 121 has an inner contour that matches the shape of the cross-section of the rod 321. Its corner or planar mating structure can provide clear circumferential positioning, thereby achieving a reliable anti-rotation effect.

[0062] Understandably, by designing the rod 321 and the blind hole 121 as non-circular structures with matching cross-sectional shapes, and by using clearance fit or transition fit, it is ensured that the rod 321 can be smoothly inserted into or pulled out of the blind hole 121 along the axial direction, while also effectively restricting the circumferential degree of freedom of the rod 321 within the blind hole 121, preventing the rod 321 from rotating unexpectedly during use or adjustment.

[0063] In some embodiments, the outer periphery of the rod portion 321 is provided with a plurality of telescopic grooves arranged along its axial direction; the locking member 32 further includes an elastic telescopic structure 33 disposed in each telescopic groove, the elastic telescopic structure 33 having a first state of extending radially outward along the rod portion 321 under the action of elastic force, and a second state of contracting radially inward under the action of external force; the inner wall of the blind hole 121 is provided with a plurality of locking holes 122, when the elastic telescopic structure 33 is in the first state, its extended portion is locked into the corresponding locking hole 122 to lock the rod portion 321 and the handle portion 12 in the axial direction.

[0064] For example, the elastic telescopic structure 33 refers to a mechanical component with elastic restoring capability that can extend and retract radially along the rod portion 321. In its natural state, it pops outward to engage with the corresponding locking hole 122, thereby locking the relative position of the rod portion 321 and the blind hole 121. For example, the locking hole 122 is a groove formed radially recessed along the blind hole 121, which can accommodate at least a portion of the elastic telescopic structure 33 in its popped-out state and provides a stop surface for its engagement with the elastic telescopic structure 33.

[0065] For example, the telescopic groove is a recess formed radially indented along the rod portion 321, extending inward from the outer surface of the rod portion 321. For example, the telescopic groove is a blind groove that does not penetrate the inner cavity of the rod portion 321, and each telescopic groove independently accommodates a telescopic block 331; the depth of the telescopic groove is generally slightly larger than the dimension of the telescopic block 331 in its direction of movement, to ensure that the telescopic block 331 can be completely submerged in the groove in the second state without exceeding the outer contour of the rod portion 321, while in the first state, a sufficient portion protrudes to reliably engage with the locking hole 122 in the blind hole 121.

[0066] Understandably, the multiple locking holes 122 arranged axially provide multiple discrete and clearly defined locking positions for the insertion depth of the shaft 321. When adjustment is required, applying sufficient axial tension to the shaft 321 causes the telescopic block 331 to switch to the second state under pressure, thereby sliding out of the current locking hole 122; when the shaft 321 is moved axially to the target position, the telescopic block 331 automatically pops out and resets to the first state under the action of elasticity, accompanied by a clear "click" or tactile feedback. This allows the extension length of the handle sleeve 20 to be adjusted quickly, in stages, precisely and reliably, allowing users to set the racket length and balance point according to their personal preferences without tools.

[0067] In some embodiments, the elastic telescopic structure 33 includes an elastic element 332 and a telescopic block 331; the telescopic block 331 is slidably disposed in the telescopic groove along the radial direction of the rod portion 321, and the elastic element 332 is connected to the telescopic block 331 and the groove of the telescopic groove, for providing the telescopic block 331 with an elastic force to move it out of the telescopic groove.

[0068] For example, the elastic element 332 can be a coil spring, wave spring, disc spring, or elastic rubber column, etc. For example, one end of the elastic element 332 abuts against the telescopic block 331, and the other end abuts against the bottom of the telescopic groove, to provide a stable, linear radial outward thrust to the telescopic block 331. For example, the telescopic block 331 is a plunger or slider made of metal or high-strength engineering plastic, and its side that slides in conjunction with the telescopic groove may have a coating or structure to reduce friction. For example, a limiting structure can be provided between the telescopic block 331 and the telescopic groove to prevent it from completely disengaging, for example, a flange provided on the telescopic block 331 engages with a locking platform at the opening of the telescopic groove.

[0069] In some embodiments, the locking member 32 further includes a control structure disposed on the ball portion 322, the control structure being connected to all telescopic blocks 331 and used to control all telescopic blocks 331 to switch between a first state and a second state.

[0070] For example, the control structure, connected to each telescopic block 331, can transmit externally input operating force to all telescopic blocks 331, driving them to overcome the elastic force of their respective elastic elements 332 and move radially inward, thereby disengaging them from their respective blind holes 121 and locking holes 122, and the whole structure switches from the first state to the second state. When the operating force is removed, each telescopic block 331, under the restoring force of the elastic element 332, can be radially ejected outward to return to the first state, realizing centralized and unified control of the telescopic state of all telescopic blocks 331.

[0071] It is understood that in this embodiment, the extension and retraction states of multiple telescopic blocks 331 are converged to the adjustment of the control structure of the ball part 322. The user does not need to touch or operate each telescopic block 331 separately. By simply controlling the control structure of the ball part 322, the state of all telescopic blocks 331 can be changed, thereby quickly completing the unlocking and locking of the axial position of the rod part 321.

[0072] In some embodiments, the control structure includes a rotating ball 34, a winding reel 35, and multiple connecting lines 36; the rotating ball 34 is rotatably disposed on the outside of the ball portion 322; the winding reel 35 is disposed on the inside of the ball portion 322 and is coaxially fixedly connected to the rotating ball 34; one end of each connecting line 36 is connected to the winding reel 35, and the other end passes through the inside of the rod portion 321 and is connected to a telescopic block 331; wherein, by rotating the rotating ball 34, the winding reel 35 can be driven to wind up or release the connecting lines 36, so as to synchronously pull all the telescopic blocks 331 to retract to the second state, or allow them to return to the first state under the action of the elastic member 332.

[0073] For example, a portion of the rotating ball 34 is exposed outside the ball portion 322, and its surface may be provided with anti-slip texture to facilitate rotation under force. For example, the winding reel 35 is located in the internal cavity of the ball portion 322, and its rotation axis is fixedly connected to the rotating ball 34, thereby realizing direct power transmission. For example, one end of multiple connecting wires 36 is connected to one end of a coupling wire, and the other end of the coupling wire is connected to the rotation axis; the other ends of the multiple connecting wires 36 pass through a pre-set axial channel inside the rod portion 321, and finally connect to the inner end of the corresponding telescopic block 331.

[0074] In this embodiment, when the rotating ball 34 is rotated in one direction, the winding reel 35 rotates synchronously, winding and tightening all the connecting wires 36, thereby applying a radially inward pulling force to each telescopic block 331, overcoming the elastic force of the elastic element 332, causing all telescopic blocks 331 to synchronously retract into the telescopic groove to the second state, disengaging from the engagement with the locking hole 122 in the blind hole 121. At this time, the rod 321 can move freely axially within the blind hole 121. When the rotating ball 34 is rotated in the opposite direction, the winding reel 35 reverses to release the connecting wires 36, and each telescopic block 331 is pushed radially outward by the elastic force of its own elastic element 332, returning to the first state, and locking into the corresponding locking hole 122 when the rod 321 moves to the corresponding position.

Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
